TELEWAVE MODEL 44 SERIES BROADBAND RF WATTMETERS
The Telewave Model 44 series RF Wattmeters are compact, versatile instruments used for direct measurement of forward and reflected RF power. Thanks to their wide band capability and dynamic range, no elements, inserts, or bandswitching is required.

Five power scales are provided, The 500 watt scale will test most high powered transmitters, while the 5 watt scale makes it simple to tune low powered portables. The excellent stability of these ranges and the ability to switch them from one power range to another to check the calibration eliminated the need for a secondary standard to check calibration

TELEWAVE LOW POWER COAXIAL RF TERMINATIONS
Telewave offers a full selection of coaxial loads with extremely low VSWR. Applications include hybrids, isolators power monitors, wattmeters, and coaxial line terminations.
All loads are built ruggedly to withstand bench or field use. Power rating provides substantial overload protection.
Unlike liquid dielectric loads, these dry dielectric loads can be operated in any position.
Connectors have Silver Plated centre pins for optimum conductivity. (Excluding the TWL-

TELEWAVE COAXIAL RF TERMINATIONS (50 TO 150 WATTS)
Telewave coaxial loads feature extremely low VSWR. Applications include hybrids, isolators, power monitors, wattmeters, and coaxial line terminations.
Telewave loads are custom machined to withstand bench or field use. The conservative power rating provides substantial overload protection. Unlike liquid dielectric loads, these dry dielectric loads can be operated in any position.
